Being somewhat of an RPG user I suspect your F-specs for the PCMASTER file is in error FPCMASTERIC F nnnnRllAM DISC F KIMAGE dbnameL7 F KITEM item F KLEVEL password F KDSNAMEPCMASTER The spacing here is not correct for a cut 'n paste for RPG, but it will suffice for this. The nnnn is the record length. The ll is the key length. The rest is fairly straight forward. The KIMAGE line might be where your problem is. The L is Read/Write shared mode with dynamic locking. The next digit, a 7 in this case, is the mode one would pass to a DBGET/DBFIND. (7 does just a DBGET) Under this definition a program may read records. To do writes I would us a 97 in place of L7. The 9 does dataset locking. Our shop/software uses a 2nd opn of the DB under a different control block for updating the base. For reading the KIMAGE would have one name. For writing the KIMAGE would have a different name. You can use file equations outside the program to point both KIMAGE names to the same physical db. Hope this helps. See pages 4-34 & 4-35 in RPG manuals. Mine are a tad old so pages may not be exact in your manual. If you have one. If it is online look for the string 'Calculated Read'.
